What can you do if you have no car insurance and you are being sued for an accident your wife that you were separated from and now divorced from had caused?

You can hire a lawyer that will plead your case in court but that will cost you a lot of money. I'll assume that you don't have a lot of money otherwise you would have had car insurance. You will have to face the face that you have done two things wrong. You have caused an accident and you have driven a car without insurance. At times like these we need to accept what we have done and pay the price.
